Preheat oven to 350 degrees and prepare a Bundt pan by spraying with baking spray.
Add all of the cake ingredients to a large mixing bowl. Beat mixture with a hand mixer on medium speed for 2 min.
Pour mixture into prepared bundt pan and bake on 350 for approximately 45 minutes or until a tooth pick comes out clean in center of cake.
Cool for 15 minutes in the pan and then transfer the cake onto a plate.
For the glaze, Melt the margarine in a small saucepan over low heat.
Add the brown sugar and stir until dissolved. Let it gently bubble for about 1 minute.
Remove from the heat and let cool for 2 minutes.
Whisk in the powdered sugar until smooth.
Add the Rich whip and stir until smooth.
Pour over your Bundt cake while the glaze is still slightly warm.
Garnish with chopped candied pecans, if desired.
